Street GL

Streets GL is a real-time 3D map renderer built for visualizing OpenStreetMap data with a heavy focus on eye-candy features.

The whole project is written in Typescript. For rendering it uses a custom low-level library that wraps WebGL2 API, and for managing the rendering pipeline it uses a simple render graph (or frame graph) implementation. Geometry generation is done on the fly; supported map features include but are not limited to complex building shapes (according to the de-facto standard Simple 3D Buildings schema), roads and paths, trees, etc.

The goals of this project include providing a way to explore the feature-rich OSM database in 3D, promoting open data, and offering a way for the mapping community to easily validate the map by visual means.
